Peach tree named ‘Snow Belle’

ABSTRACT

A new and distinct variety of peach tree ( Prunus persica ). The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features:
         1. Tree having a vigorous, upright growth habit.   2. Tree being a regular and productive bearer of large size fruit.   3. Fruit having firm, white flesh with a very good flavor and eating quality.   4. Fruit having an attractive red skin color.   5. Fruit with good storage and shipping qualities.

Botanical designation: Prunus persica.

Variety denomination: ‘Snow Belle’.

BACKGROUND OF THE VARIETY Field of the Invention

In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and asexual reproduction of orchard trees, and of which plums, peaches, nectarines, apricots, cherries, almonds and interspecifics are exemplary. It was against this background of our activities that the present variety of peach tree was originated and asexually reproduced by us in our experimental orchard located near Modesto, Stanislaus County, Calif.

PRIOR VARIETIES

Among the existing varieties of peach trees, which are known to us, and mentioned herein, ‘Super Lady’ Peach (U.S. Plant Pat. No. 15,578) and ‘Snow Fox’ Peach (U.S. Plant Pat. No. 27,790).

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

ORIGIN OF THE VARIETY

The new and distinct variety of peach tree (Prunus persica) was developed by us in our experimental orchard located near Modesto, Calif. as an open pollinated seedling originating from seed collected from ‘Snow Fox’ Peach (U.S. Plant patent application Ser. No. 14/544,568). A large group of these open pollinated seedlings were budded to older established trees of ‘Nemaguard’ Rootstock (non-patented) to enhance earlier fruit production. Under close and careful observation the present budded seedling exhibited desirable fruit and tree characteristics and was selected in 2009 for additional asexual propagation and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

In 2009 asexual reproduction of the new and distinct variety of peach tree was by budding to ‘Nemaguard’ Rootstock (non-patented), as performed by us in our experimental orchard located near Modesto, Calif., and shows that reproductions run true to the original tree and all characteristics of the tree and its fruit are established and transmitted through succeeding asexual propagations.

SUMMARY OF THE NEW VARIETY

The present new and distinct variety of peach tree (Prunus persica) is of large size, vigorous, upright growth and a regular and productive bearer of large size, white flesh, clingstone fruit. The fruit is further characterized by its moderately juicy, firm flesh and having an attractive red skin color. In comparison to its seed parent ‘Snow Fox’ Peach (U.S. Plant patent application Ser. No. 14/544,568) the fruit of the new variety is approximately 3 weeks earlier in maturity. In comparison to the commercial variety ‘Super Lady’ Peach (U.S. Plant Pat. No. 15,578) the fruit of the new variety has white flesh compared to yellow and is larger in size.

DESCRIPTION OF THE PHOTOGRAPH

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new peach variety. The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a single fruit divided in its suture plane to show flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked (shipping ripe) from a 7 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

Any variety observed during     indexing of plant characteristics with abnormal fungus, bacterial,     virus or insect susceptibility is destroyed and eliminated from our     breeding program. No atypical resistances/susceptibilities have been     noted under normal cultural practices. The present new variety of     peach tree, its flowers foliage and fruit herein described may vary     in slight detail due to climate, soil conditions and cultural     practices under which the variety may be grown. The present     description is that of the variety grown under the ecological     conditions prevailing near Modesto, Calif. 

The invention claimed is:
 1. A new and distinct variety of peach tree (Prunus persica), substantially as illustrated and described.
